## Providing Assets
Although not essential, you will most likely want to provide several assets to Dashy. All web assets can be found in the `/public` directory.
For example:
- `./public/conf.yml` - As mentioned, this is your main application config file
- `./public/item-icons` - If you're using your own icons, you can choose to store them locally for better load time, and this is the directory to put them in. You can also use sub-folders here to keep things organized. You then reference these assets relative this the direcroties path, for example: to use `./public/item-icons/networking/netdata.png` as an icon for one of your links, you would set `icon: networking/netdata.png`
- Also within `./public` you'll find standard website assets, including `favicon.ico`, `manifest.json`, `robots.txt`, etc. There's no need to modify these, but you can do so if you wish.
- `./public/item-icons` - If you're using your own icons, you can choose to store them locally for better load time, and this is the directory to put them in. You can also use sub-folders here to keep things organized
- Also within `./public` you'll find standard website assets, including `favicon.ico`, `manifest.json`, `robots.txt`, etc. There's no need to pass these in, but you can do so if you wish
## Basic Commands
This is easy to do using [Docker Volumes](https://docs.docker.com/storage/volumes/), which lets you share a file or directory between your host system, and the container. Volumes are specified in the Docker run command, or Docker compose file, using the `--volume` or `-v` flags. The value of which consists of the path to the file / directory on your host system, followed by the destination path within the container. Fields are separated by a colon (`:`), and must be in the correct order. For example: `-v ~/alicia/my-local-conf.yml:/app/public/conf.yml`
Now that you've got Dashy running, there are a few commands that you need to know.
## Running Commands
The following commands are defined in the [`package.json`](https://github.com/Lissy93/dashy/blob/master/package.json#L5) file, and are run with `yarn`. If you prefer, you can use NPM, just replace instances of `yarn` with `npm run`. If you are using Docker, then you will need to precede each command with `docker exec -it [container-id]`, where container ID can be found by running `docker ps`. For example `docker exec -it 26c156c467b4 yarn build`.
The project has a few commands that can be used for various tasks, you can find a list of these either in the [Developing Docs](/docs/developing.md#project-commands), or by looking at the [`package.json`](https://github.com/Lissy93/dashy/blob/master/package.json#L5). These can be used by running `yarn [command-name]`.
- **`yarn build`** - In the interest of speed, the application is pre-compiled, this means that the config file is read during build-time, and therefore the app needs to rebuilt for any new changes to take effect. Luckily this is very straight forward. Just run `yarn build` or `docker exec -it [container-id] yarn build`
- **`yarn validate-config`** - If you have quite a long configuration file, you may wish to check that it's all good to go, before deploying the app. This can be done with `yarn validate-config` or `docker exec -it [container-id] yarn validate-config`. Your config file needs to be in `/public/conf.yml` (or within your Docker container at `/app/public/conf.yml`). This will first check that your YAML is valid, and then validates it against Dashy's [schema](https://github.com/Lissy93/dashy/blob/master/src/utils/ConfigSchema.js).
- **`yarn health-check`** - Checks that the application is up and running on it's specified port, and outputs current status and response times. Useful for integrating into your monitoring service, if you need to maintain high system availability
- **`yarn build-watch`** - If you find yourself making frequent changes to your configuration, and do not want to have to keep manually rebuilding, then this option is for you. It will watch for changes to any files within the projects root, and then trigger a rebuild. Note that if you are developing new features, then `yarn dev` would be more appropriate, as it's significantly faster at recompiling (under 1 second), and has hot reloading, linting and testing integrated
- **`yarn build-and-start`** - Builds the app, runs checks and starts the production server. Commands are run in parallel, and so is faster than running them in independently
- **`yarn pm2-start`** - Starts the Node server using [PM2](https://pm2.keymetrics.io/), a process manager for Node.js applications, that helps them stay alive. PM2 has some built-in basic monitoring features, and an optional [management solution](https://pm2.io/). If you are running the app on bare metal, it is recommended to use this start command
But if you're using Docker, then you'll need to execute them within the container. This can be done by preceding each command with `docker exec -it [container-id]`, where container ID can be found by running `docker ps`. For example `docker exec -it 26c156c467b4 yarn build`. You can also enter the container, with `docker exec -it [container-id] /bin/ash`, and navigate around it with normal Linux commands.
